I don't know d610 it has it. I have d600.

To disable it go to registry by following the path in the previous page. Change DisableMicFromPlayback from 01 to 00. Restart and when you double click on the speaker icon in the system tray, you will notice an additional column for the microphone. The microphone will be then muted when you unmute you will hear the surrounding noise.
DisableMicFromPlayback is the line to monitoring the mic line in. its not the gain of an internal mic, i remember.
thats pretty good to rec with line in cause you hear what comes in, but with that terrible issue, cant be a serious thing!
but good quote: have try it someone? but im sure there isnt an internal mic nomore at d610.

"EmulateAllMasters" set 01 to 00
and reboot, the whine is almost away!!

thats cause the win gain is full open usual, but that amplifys the terribel issue of whine of the c-major chip. (i think the amp of this chip is too strong for itself,,,)

What exactly does this registry setting control? I tried this, and it did not seem to make a difference at all. The headphone whine is still present.

Als0 - I tried muting the internal mic, and it did not seem to make any difference either.

the first one it doesnt work for me also, but after a few booting and figering around, it happens...
perhaps download an old sigmatel driver from dell and replace it.
im sure if you press mute, nothing changed, but if, then you are ready for this fix.
but forget about that to spend much time about that, thats the job for dell!! you know what im talkin

can headphone whine be repaired?

I've been in contact with Dell support, and they've had me try the following to no avail:

1. install latest audio drivers
2. disable track stick
3. unplug AC adapter (this >slightly, improved the problem)

Now they are offering to have me send the system back for depot repair. Should I bother? They never answered my question (posed twice - all via email) as to whether this problem can actually be fixed, or whether it is a design flaw.

Anybody have input? Can this problem be fixed?

see thats a serious prob and every d610 is affected by.
techs and i tryed everything (techs was twice here, about 5 hours in all):
work the sigmatel driver
disable wifi, alp, stick,
replace mainboard
hardware disable wireless, alp, keys, stick, modem
(much more is not built in!)
and nothing get the trick
so im sure its a design flaw - dell has not tested it - dell let test by his customers.
but after the smoke get clear:
they have now to check the mainboard carefully to fix it, but that need time, a lot of time. or they take the mainboard form an other manufactor with other chips, whatever
but dell has first to work out a solution for all theire customers who already own a d610
and then they have to realize, there are two independent probs, first one, who exist almost over 3 years and affected by every dell laptop since then is the WHINE, the typical dell seeshell sound
and the second is, who's affected above all the new d-serie, the electric noise from what.
i tel a lot with support, and they came out slowly but they realize the issue gradualy
so im sure in the future this prob has been solved, dell comes very early with HD-audio
but we are not interestet in future - we are interestet by now.

Yeah, I just sent an email to Dell about this. If they don't find something to solve the issue in the next couple of days, I'm going to return it. It has a lot of positive features, but I'm not going to pay $1700 for a computer that I'm going to use for at least 3/4 years when I can't listen to music or play dvds without being bugged by this noise. It's a major blunder on Dell quality control's part that they didn't notice this problem when they released it. I mean, come on, this is a latitude, not some cheapy inspiron.

one thing to note, i have a D810 and have absolutly NO buzz, whine or any other kind of noise in my headphone port. I did not get the 56k internal modem on my system. It's possible this may be a factor? just thought it was worth letting you guys know. Good luck.

it's probably a driver problem, because by changing the 01 to 00 in the registry, it fix the problem on my computer. I hope that they will release new audio driver soon for you.

Important to note: before the registry hack, the humming was loud but it was constant (it did not change when you increased the sound volume). After the hack, as you increase the volume, the humming does get louder (at least on my system) to the point where on the highest volume, the humming sounds like it was before the hack.

yeah, that was alwys a theorie of mine, that the internal modem makes the whine, but not the noise. the noise, would say is d610 spezific and its bug somewhere on meinboard/chipset.

thats exactly that was i said before:
usual the gain of windos is full open, but with this regedit fix you can the win gain put on an equal to the source of the sigmatel control. and when you open the gain full, there you are exactly on the level before.

Here's what Dell tells me:

"The background noise is mostly present when
the operating system or DVD player volume is turned completely down or
muted and the speaker sound volume is turned completely up. So please
avoid doing the same and verify. Also let us know whether the background
noise issue occurs only in the DVD drive or in any other application as
well."

The noise, especially the annoying whine, occurs even when the dvd drive is removed! Well, I'll respond and let y'all know how it goes.

Couple of updates:

On a barebones system (no drivers either), there is no humming because there is no audio driver of anykind. Once you install the C-Major driver, the humming appears. So that's that.

I physically took out the modem. It made not difference, the humming is still there.

The humming stays the same whether running on battery or AC.

Someone from the official dell forums suggested to install the realtek ac'97 audio drivers:
RealTek Drivers

Direct download link: ftp://210.51.181.211/pc/ac97/alc650/wdm_a370.exe

I don't know if they're the same as dell's, are official, if they work, or take care of the problem. I haven't tried them yet.

EDIT: WARNING: I JUST TRIED THEM AND THEY YIELD A BSOD. WINDOWS SAYS THEY DID NOT PASS THEIR LOGO TESTING.

description of headphone noise

Here's my description of the headphone noise problem:

1. With headphones plugged in to the audio out, there is a background "hiss" or "hum."
2. Whenever the mouse is moved, window resized/redrawn, etc, the headphone picks up feedback that is even louder and worse than the background hum.
3. When the HD is running, the noise seems to nearly disappear (?)
4. When running off battery power, the noise is reduced but still present
5. For me, the registry change "emulate all masters" that has been described in these forums does nothing to change this problem

anybody try the following gadget?

even if this headphone issue is someday resolved, I'm curious about this gadget. If it provides better sound, it may be worth the $30.

Has anyone installed linux on their D610 and if so does that resolve the headphone issue?

Too bad that driver didn't work, angel, I was hoping it was!

Ok, so now dell is telling me this :

"As per the information provided by you, your system motherboard will
need to be replaced in order to resolve the described issue. Please let
me know if I should proceed arranging depot service for motherboard
replacement or would you like to opt for system exchange as you can also
avail exchange offer."


zzigall, didn't you already go through all of this, but to no avail? Should I even bother?
